Claims.

to support the heel and quarter sections of the upper, when the shoe isworn the stiiener tends,

by reason of its resiliency under the damp heatv of the foot, to returnto its original shape and the, shoe becomes distorted, breaks down, anddoes not conform to the foot. If the sti'eners are less than amplyheavy, they lack the strength to afford proper support and distortion isagain the result. Because of this many shoemakers have adopted inferiormaterials which are stifl and less comfortable to the wearer thanleather 20 or fibre reinforcements.

A principal object of my invention, therefore, is to provide an improvedshoe having a fibrous counter reinforcement which will conform closelyto the last in manufacture and be strong and comfortable and hold theshape of the last in the finished shoe. Another object-is to provide ashoe having an improved toe construction.

Also, inasmuch as toe and counter stiifeners are sold as articles ofindependent manfacture,

o a further object of my invention is to provide 35 of thisspecification:

counter and toe reinforcements oi' improved construction. Other andfurther objects will appear from the following specication. Y

Referring to the drawings which form a part Figure .1 is a plan view ona reduced scalo of a counter blank prepared in accordance with myinvention. f

Figure 2 is a sectional view taken on line 2 2 40 of Figure 1.

50 its lining, and illustrates the manner in 4which 55 ments, have beenassembled, the upper beingthe counter blank may be. inserted between theupper and lining preparatory to lasting the shoe. Figure 'I is aperspective view of a last on which the shoe parts, including `myimproved reinforcewi.' .3s-ss) broken away at a quarter section of theshoe to disclose the relationship of the several parts.

Figure 8 is a side elevation of my improved shoe, the rear portion beingsho-wn in section and the upper being broken away over the toe tip toreveal my improved toe construction.

Figure 9 is a fragmental section on a greatly enlarged scalaillustratingin exaggerated proportions the form of the counter stiffener in thefinished shoe.

In carrying out my inventionl utilize an amply heavy leather vor fibrecounter blank I0 of conlventional variety and of a configuration properfor the shoe into which it is to be assembled, the marginscl I of theblank being sklved in the usual manner. The size of the blank, however,is somewhat smaller than would ordinarily be required.

'I then weaken the blank over the areas which normally would besubjected to the greatest strain in the lasting operations. To do this Iprefer to form slits orr gashes I2- I2 and I3--I3 etc., in the outersurface of the stiieners oblique to the planes of the surfaces of thestifeners. As

lshown; the slits are curved andthe curves are convex toward thedirection in which'fthe blank is drawn about the last.

As shown, the incisions I2 are formed in the middle of the counterblank, which 'is the back of the shoe, and are curved in oppositedirections on either side of the centre, each set of cuts beingsubstantially parallel. The two sets of incisionsy I3 are locatedrespectively in the wings of the counter adjacent to the cuts I2. Iprefer to extend'the outs only part way through the counter blank, asshown, but they may be extended entirely through to form slits, ifdesired.

The toe stiilener 30 consists of an amply heavy leather or fibre blankskived and contoured in the usual manner and Ahaving incisions 3I-3Iformed therein to extend angularly inward, in

all respectssimilar to the cuts I2 and I 3 formed in the counterblank.4v

'Ihe blanks thus prepared are then wetted or tempered and a coat ofadhesive I5, such as the usual shoemakers paste, is applied to both sur-.faces of the respective blanks and to the facing surfaces of the upperi1 and lining I8 ofthe shoe, whereupon the blanks are inserted ininteriining relation between the upper and lining, as indicated inFigure 6. f

The upper parts, including the reinforcements, are then conformed toalast on which the .shoe is assembled in the usual manner, the wings 0fthe counter blankbeing drawn forwardly and the margins of the upper,lining and reinforcements' b'eirgv pulled over the last and secured to asole member 2l by means of tacks 22 or other' suitable means.

It will be found that the top line and bottom line of the counterstiffener will conform closely to the last with very little shirring orplaiting,

. because the intermediate slitted portions of the stiffener will giveor stretch slightly and the slits will open up to provide roughenedsurfaces, obtaining a-firm .bond with the paste which iiows into theslits. When the paste congeals, it serves to restiffen the constructionand hold it in its v'lasted shape.

All of the shoemaking operations shown re'- ferred to are customary andusual except for the formation of the incisions in the fibrousreinforcing parts. Also, the further operations necessary to completethe shoeV may be the same as are customarily performedin making turned,Mc- Kay or welted constructions and no detailed de'- scription of suchshoemaking practices are necessary for a complete disclosure of mypresent invention.

Reinforcements for counters. and toes are usually manufacturedseparately and sold to the 4Shoemaker either `in fiat blanks orpremolded substantially to the sizeland conformation re-` quired for theshoex Stiffeners having my im-` proved construction may be similarlypremol'ded," if desired, without sacrificing any of the advantages heretaught.

' The shoe 'embodying my improved stiffeners is strong and comfortableand the top line and bottom line at the counter portion maintain theirshape andshow -no tendency to sag or break down. The weight of thecounter reinforcement being adequate, there is ample strength andstiffness at the heel and quarter sections of the upper while theweakening effect of the incisions? over the areas of greatest strainrobs the material ofl its elasticity at these points to such a degreethat it cannot warp by reason of its tendency to` re sume its normalflat condition. Any `such tendi5.

illustrative of my invention as dened in the appended claims.

I claim:

1. A shoe comprising an upper and a lining therefor, a fibrousreinforcement interlined between said upper a-nd lining, saidreinforcement having a plurality of cuts formed in the outer surfacethereof intermediate the top line and the sole of the shoe, certain ofsaid cuts being located centrally of the reinforcement and extendingapproximately horizontal and other of said cuts extending approximatelyvertical and located forwardly of the horizontal cuts, and adhesivebonding the outer surface of the reinforcement to the inner surface ofthe upper,said adhesive extending into said cuts.

2. A shoe comprising an upper and a fibrous reinforcement lining saidupper, said reinforcement having a plurality of open scores formed Atherein extending angularly inward from the outer lsurface thereofintermediate the top line` andthe sole of the shoe, `said cuts beinglocated centrally of the reinforcement and extending substantiallyhorizontal, and vadhesive bonding the outer surface of the reinforcementto the inner surface of the upper, said adhesive extending into saidscores.

3. A shoe comprising an upper and a fibrous reinforcement lining saidupper, said reinforcement having a plurality of curvilinear incisionslformed therein extending angularly inward. from the outer surfacethereof over the greater portion`of a central area intermediate the topline and the sole of the shoe 'transversely of the back seam of theshoe, and adhesive bonding the outer 3 surface 'of the reinforcement tothe inner surface `of the upper, said adhesive extending into theincisions.

' 4. A shoe reinforcement of the character de- 'I scribed comprising afibrous sheet vhaving a plurality of curvilinear scorings formed in asurface thereof over the greater portion of a central area intermediateopposite margins, the curves of the scorings on opposite sides of thecentre of the sheet being convex in the direction of the adjacentmargins of thesheet.
